SPECIFICATION forming part of LettersPatent No. 592,043, dated October 19, I897.

- Application filed April 24, 1897 Serial No. 633,720. (No model.)

To aZZ whom it may concern:

Be it known that I, GEORGE BANSALL, residing at Lilly, in the county of Cambria and State of Pennsylvania, have invented a new and useful Automatic Switch, of which the following is a specification.

My invention relates to a novel arrangement of parts for shifting the switch-points, and also providing a simple means carried by the car for this operating mechanism.

The object of my invention is to provide such an arrangement which is automatic and positive inits action, so that the switch-points can be shifted by the motor of the car. I accomplish this by connecting with the tie-rod joining the two switch-points bell-crank levers and connecting with the bell-crank levers pivoted segments which are engaged by suitable means, carried by the car, for depressing them whereby the rails are shifted. The segments are arranged in pairs, and apair is placed on each side of the track, so that a car approaching the switch in either direction can engage with the segments to properly shift the points. I also arrange the automatic device carried by the car so that it can be shifted to either side according to which pair of segments it is desired to operate.

In order that my invention may be fully understood, I will proceed to describe the same with reference to the accompanying drawings, in which-- Figure l is a view showing my invention in practice. Fig. 2 is a plan View of the switchoperating mechanism, and Fig. 3 is a detail elevation of the automatic means for shifting the switch. I

In the said drawin gs,A represents the rails of the main track, A the switch-rails, and B the switch-points, which are all arranged in the usualway. Oneach side of the main and switch rails I locate the mechanism for shifting the switch-points. As it will be seen from the drawings, the several parts are placed in suitable metalliccasings O,sunk in the ground so that the removable-metal covers will be flush with the surface of the street.

The two switch-points are connected by a tie-rod D, having an extension D and crosshead D which work in the central portion of the metal casing O, and to these cross- -heads I connect the bell-crank levers E by opposite side will be flush with the cover 0.

To further explain the arrangement, referonce is had to Fig. 1, in which the switchpoints are set to throw the car onto the switchrails. If the car is to run on the main rails, the automatic device carried by the car is shifted to depress the segments, which causes the switch-points to move, and as they are moved the segments on the opposite sides are raised. Should the next car in the same direction have to run on the switch-rails, the automatic device is shifted to the other side of the car to depress the segment on that side. It will be seen that the inclined faces 'of the segments on which the automatic device runs are oppositely arranged and are located on each side of the switch, so that should acar be traveling in the other direction, either on the main rails or switch-rails,

.the segments will be in proper position to be engaged by the automatic-device for shifting the switch-points. 8 5

The automatic device for operating the seg ments, to shift the switch-points, consists of a pair of wheels or rollers H, carried by a shaft H, supported in a track I, carried beneath the car-platform. The shaft is adapted 0 to be shifted in the bracket so that either se -ment can be engaged, and the means for shifting the shaft consists of a grooved pulley J, carried on a shaft or rod K, journaled to the front of the car, and a cord or rope L, 9 5 connected near each end of the shaft and having its middle portion passedaround the grooved pulley. The upper end of the shaft is provided with a handle M, which slides on a segment M. This handle is limited in its movement on the segment by the pins N, placed at each end thereof. The operation of this part of my device will be readily understood. The wheels or rollers run normally on the ground on each side of the track, and are adapted to run on the inclined face of the segments when it is desired to shift the switchpoints.

From the foregoing it will be seen that I have provided a simple arrangement for shifting ments adapted to be engaged by means carried on the car whereby the switch-points are shifted said means consisting of a pair of wheels mounted on a shaft which is carried by a bracket, said shaft having means in 0011- nection with it for shifting it laterally in the bracket consisting of a pulley carried 011 the shaft or rod provided with the operatinghandle at one end and a rope or cord connected with the shaft near each end thereof and having its middle portion passed around the pulley, substantially as shown and described.

GEORGE BANSALL.
